Our last blog post introduced OLED technology to many of our readers, and mentioned some of the issues keeping it from leading the biggest breakthrough in home entertainment since the cathode ray tube. Chief among these were high costs and low lifespans. That being said, developments from LG and DuPont signal that commonplace OLED TV may be closer than we think. Read on for more details on how close we are to thinner screens, wider viewing angles, redder reds, and bluer blues.
About those blues: with lifespans a fraction of those of other colors, the blue OLEDs were a big part of the problem. It certainly wouldn’t do to have a display that worked fine for 10 years or more – with the exception of little things like a nice sky. This shorter operating time comes as a result of miniscule differences in diode construction necessary to achieve the various color wavelengths: the configuration for blue breaks down more easily than for other colors. In any case, engineers claim that they have achieved blue OLEDs capable of staying lit for 30,000 hours or more, reaching that 10 year benchmark.
Gone are the days of the simple CRT: the TV market currently resembles an alphabet soup more than ever – this newest technology is referred to as “AMOLED” (for Active Matrix OLED). Regardless of names, though, the benefits are promising. Who wouldn’t want the thinnest screens, the lowest power usage, and, if this article is correct, affordable pricing by 2014? And, of course, you’ll be the first to know when these replacement bulbs are available at Bulb Direct.
